Description

  The present invention relates to an ink supply system for an intaglio printing machine that prints securities such as banknotes and checks, passports, IDs, and other similar articles.

  In the field of multicolor intaglio printing, it is necessary to fill the fine and deep markings of the intaglio with the correct amount of ink in order to obtain good print quality, but at the same time more ink than is necessary to satisfy the fine engraving. There is a need to improve the operability of the printing press and reduce ink consumption by minimizing the amount and the amount of ink transferred to the non-engraving area of the intaglio.

  Examples of prior art printing presses are given by US Pat.

  In the state of the art for intaglio printing machines and processes, the ink supply system is provided with a rough adjustment of the amount of ink along the axis of the printing cylinder, but no means for adjusting the circumference of the cylinder is provided. .

For example, a means for more precise adjustment is known from US Pat. No. 6,057,049, which is characterized by a duct having a plurality of ink retaining recesses having various depths corresponding to the depth of the printing plate. An intaglio printing press having a general configuration is disclosed. This printing press is not commercialized at all. This printing press has the following drawbacks.
Machine structure uses only direct ink supply process.
The ink holding recess on the duct cylinder cannot accurately match the engraving pattern on the intaglio.
The duct / blade arrangement requires a continuous cylinder surface and is incompatible with the plate clamping device. Engraving is much easier to manufacture, install and service than a set of cylinders.
The rigidity of the ink blade is high, and the ink blade cannot be precisely controlled by adjusting the screw.
The gap between the ink blade and the duct roller allows a large amount of ink to adhere to the non-engraved surface of the duct and then to the non-engraved surface of the intaglio, so that no ink is saved.
Further reduction in the gap between the ink blade and the duct will inevitably cause the blade to contact the duct and damage both the blade and the body surface.

  Other systems for improving the accuracy of ink adhesion and reducing ink consumption have been developed in the prior art, for example US Pat. The contents of the publication are referred to as an integral part of the present application. The patent application discloses an intaglio printing machine in which the selector cylinder used to deposit ink on the collector cylinder is independently driven by a drive so that the ink supply printing length on the blanket of the collector cylinder can be changed. About.

  Another example is disclosed in Patent Document 6. The contents of the publication are referred to as an integral part of the present application. In this patent application, a blanket cylinder for an intaglio printing press is formed from various layers having different properties. These layers are engraved and may be oleophilic and / or oleophobic, so that a very precise ink supply of the plate cylinder is achieved.

US Pat. No. 4,516,496 US Pat. No. 5,062,359 US Pat. No. 5,899,145 US Pat. No. 4,604,951 European Patent Application Publication No. 1442878 European Patent Application Publication No. 1445098

  The object of the present invention is therefore to improve the known machines and processes.

  It is a further object of the present invention to provide a printing press and printing process that overcomes the deficiencies of the prior art.

  Another object of the present invention is to provide an intaglio printing machine and process that is easy to operate and provides superior performance in print quality and ink savings.

  For this purpose, the invention is defined according to the claims.

  The invention will be best understood from the description of several embodiments and the accompanying drawings.

It is a figure which shows the 1st Example of the ink supply system by this invention. FIG. 3 shows a second embodiment of an ink supply system according to the present invention having a first construction of a printing press. It is a figure which shows the modification of the structure of FIG. It is a figure which shows the other structure of the printing machine which has the ink supply system by this invention. FIG. 3 shows a further structure of a printing press having an ink supply system according to the invention. FIG. 2 is a diagram showing a multicolor structure of a printing press having an ink supply system according to the present invention.

  FIG. 1 shows a first embodiment of an ink supply system according to the present invention. In this embodiment, there is a duct generally indicated by reference numeral 1, which comprises a duct roller 2, an ink adjustment blade 3 for the duct roller 2 and an ink supply 4. The duct roller 2 supplies ink to a selective ink supply cylinder 5 having an engraved surface. The surface of the selective ink supply cylinder 5 may be directly engraved, or preferably the cylinder holds an engraving with an engraving corresponding to the pattern to be inked in a predetermined color. As is known in the art, the ink supply cylinder includes a recess 7 in which clamping means (not shown) are provided to hold the printing plate 6 in place.

  The ink supply system further comprises a wiping roller 8, preferably a dry wiping roller, which is used for wiping the surface of the ink supply cylinder 5 and is thus present in the engraving of the ink supply cylinder 5. Only the ink to be left remains, and the ink present on the non-engraved surface of the cylinder 5, i.e. the non-engraved surface, is almost completely removed.

  The wiping system further includes a rubbing blade 9 for rubbing the surface of the wiping roller, and the ink thus scraped off is collected in the ink supply 4 as shown in FIG.

  Therefore, the ink supply function of the duct is separated from the ink thickness adjustment function. The duct roller 2 supplies excess ink to the selective ink supply cylinder 5 by the duct blade 3. Since the duct blade does not need to adjust the ink amount in the axial direction, it is not necessary to provide an adjusting screw. There is no need to precisely adjust the gap between the duct blade 3 and the duct roller 2. For example, if the maximum required amount of ink requires a gap of, for example, 80 micrometers, this gap can be adjusted with a wide excess tolerance of, for example, 100 to 300 micrometers. This is because the duct roller 2 does not have an ink adjustment function. The duct roller 2 is preferably coated with hard rubber or plastic (eg PVC 50 ° ShD). This coating is removable from the press for maintenance or replacement, is equipped with state-of-the-art means for adjusting the contact with the selective ink supply cylinder 5 and has a liquid circulation action for temperature adjustment. In addition, the coating preferably comprises a high speed automatic on / off device that is actuated at each rotation to avoid transfer of ink to the printing plate in the vicinity of the bending position.

  The selective ink supply cylinder 5 has an ink adjustment function and, as described above, includes a plate clamping device for the engraving 6 which is usually a chromium nickel plate. The engraving plate 6 is in rolling contact with the duct roller 2, receives excess ink from the duct roller 2, and the ink is transferred to both the engraved recess of the plate 6 and the plate surface. After the action of the dry wiping roller 8, each point of the engraving 6 holds the exact (or slightly excess) amount of ink required for the intaglio process.

  The dry wiping roller 8 is located above the duct roller 2, contacts the selective ink supply cylinder 5, and rotates in the same direction so that the two surfaces in contact with each other travel in opposite directions. Similar to the conventional wiping unit that wipes off the intaglio, the dry wiping roller 8 removes excess ink from the surface of the plate 6 and leaves the ink in the engraving. Excess ink is transferred to the surface of the dry wiping roller 8, and the rubbing blade 9 removes most of the ink from the surface of the wiping roller 8. The removed ink falls into the duct 1 by gravity and is thus recycled.

  Both the dry wiping roller 8 and the rubbing blade 9 are provided with asynchronous axial movement in order to make the roller surface wear uniform. It is preferably coated with hard rubber or plastic (eg 50 ° ShD PVC) and has a temperature regulating action (known in the art). In order to minimize the amount of ink left in the non-engraving area of the selective ink supply plate 6, the dry wiping roller 8 is preferably driven by an independent motor to optimize the rotational speed. This is in the range of a few micrometers thick. The scraping blade 9 is preferably made of steel coated with ceramic. Alternatively, the surface of the dry wiping roller may be coated with a layer of material that repels ink in order to increase the amount of recycled ink that falls into the duct due to the resultant force of gravity and centrifugal force.

  FIG. 2 shows a second embodiment of the ink supply system. In this embodiment, the duct 10 includes an ink chamber 11 having an ink spraying device 12 for spraying or spraying on a duct roller 13. In this embodiment, depending on the direction of rotation of the duct roller, it is not necessary to use a duct blade as in the first embodiment, and thus the engraved duct roller 13 (having an engraved surface or engraving is held. Can be used directly, thus simplifying the structure. The ink spraying action is synchronized with the rotation of the duct roller in order to avoid ink being applied in the non-engraving area of the duct roller and in the roller recess when the plate clamping device is provided. A wiping system having a wiping roller 8 and a rubbing blade 9 is located above the ink chamber 11. Under the rubbing blade 9, a collecting means such as a tank 14 having a pump means 15 is provided, and the collected ink is provided to an ink circuit to be sprayed.

  In the embodiment of FIG. 2, the illustrated printing press is an indirect ink supply intaglio printing press. Thus, the engraved duct having an engraving corresponding to the engraving of the plate cylinder 16 transfers the engraving ink to a chablon roller 17 having a relief 18 corresponding to the portion to be supplied with ink. Is transferred to the collector cylinder 19 before being transferred to the printing plate of the plate cylinder 16. The same collector cylinder 19 can receive different colors of ink from other ink supply units and from a chablon roller similar to the illustrated ink supply unit (not shown in FIG. 2). The indirect ink supply process in the intaglio printing process is known per se in the technical field, for example, from Patent Document 1, Patent Document 2, and Patent Document 3.

  FIG. 2b shows a modification of the structure of FIG. In this variant, identical elements are identified using the same reference numbers. This modification differs from the structure of FIG. 2 in that the collector cylinder 19 of FIG. 2 is removed and a direct ink supply structure is formed. Accordingly, this modification includes a duct 10 having an ink chamber 11 and an ink spray device 12 on a duct roller 13. Below the spray system is located a wiping system comprising a wiping roller 8 and a rubbing blade 9 and collecting means, for example a tank 14 with a pump means 15 for scraped ink.

  The engraved duct roller 13 having an engraving corresponding to the engraving of the plate cylinder 16 transfers the ink in the engraving to a chablon roller 17 having a relief 18 corresponding to the portion to be supplied with ink. The ink is transferred to the printing plate of the plate cylinder 16.

  FIG. 3 shows the structure of a printing press having an ink supply system according to the present invention. In this structure, the printing press has the direct ink supply action of the intaglio printing plate. The ink supply of the printing press is disclosed in FIG. 1, and like elements are given like reference numerals. Accordingly, there is a duct 1, a duct roller 2, a duct blade 3, and a wiping roller 8 that wipes the surface of the selective ink supply cylinder 5. The duct roller 2 is preferably a selective ink that holds the engraving 6. Ink is supplied to the printing plate 5 of the supply cylinder 5. The surface of the wiping roller 8 is rubbed by the rubbing blade 9, and the ink thus rubbed off is collected in the duct 1.

  The selective ink supply cylinder 5 then supplies ink to a transfer roller 20 having a deformable surface to infiltrate the engraving of the plate 6, which in turn transfers the ink to a chablon roller 21 having a relief 22. The chablon roller 21 then deposits the ink directly into the plate engraving of the plate cylinder 23 of the printing press.

  In the direct ink supply structure as shown in FIG. 3, it is necessary to use the transfer roller 20 for the rotation direction of the plate cylinder 23.

  FIG. 4 shows another structure of the printing press. In this construction, the printing press is an indirect ink supply intaglio printing press. The illustrated ink supply system is similar to the ink supply system of FIG. 1 or 3, and similar elements are labeled with similar reference numerals. Thus, there is a duct 1, a duct roller 2, a duct blade 3, and a wiping roller 8 that wipes the surface of the selective ink supply cylinder 5, the duct roller 2 being selectively engraved or holding the engraving 6. Ink is supplied to the surface of the ink supply cylinder 5. The surface of the wiping roller 8 is rubbed by the rubbing blade 9, and the ink thus rubbed off is collected in the duct 1.

  The selective ink supply cylinder 5 then supplies ink to a chablon roller 24 having a relief 25 which then deposits the ink on a collector cylinder 26. The collector cylinder 26 then deposits the ink in the engraving 27 of the plate cylinder 28 of the printing press. In this example, the plate cylinder 28 holds three plates.

  As such, a wiping unit 45, common in the technical field of the printing press, removes very little excess ink from the engraving and printing plate surface.

  FIG. 4 shows a printed sheet 29 which passes through a printing nip 30 formed between the plate cylinder and impression cylinder 31 as is common in the intaglio printing art. . Of course, the system according to the invention is also suitable for winding presses.

  The principle of indirect ink supply in an intaglio printing machine is known per se in the technical field to which the present invention belongs, and is disclosed in, for example, Patent Document 1, Patent Document 2, and Patent Document 3 described above. In this regard, the contents of these specifications are referred to as an integral part of this application.

  The structure of the printing machine disclosed in FIG. 5 corresponds to a four-color indirect ink supply intaglio printing machine.

  The printing press of FIG. 5 comprises separate ink supply units 30, 31, 32 and 33, each ink supply unit having a corresponding selective ink supply cylinder 34 to 37 (or the plate they hold). The engraving has a corresponding engraving 38 on the plate cylinder 39 according to the principle according to the invention. Each ink supply unit includes a duct roller 2, an ink supply, and a duct blade 3. Ink is applied to the selective ink supply cylinders 34, 35, 36 and 37 and is wiped off by the wiping roller 8 in the manner described above. Each ink supply cylinder 34, 35, 36 and 37 receives inks of different colors and has engravings corresponding to the desired pattern on the plate of the plate cylinder 39, the ink being the chablon roller 40 of each ink supply unit. , 41, 42, and 43.

  In this configuration, the selective ink supply cylinders 34, 35, 36 and 37 may have only engraving patterns corresponding to the colors that the selective ink supply cylinders must transfer. Advantageously, in another embodiment, the selective ink supply cylinders 34, 35, 36 and 37 may all be engraved with the same pattern corresponding to the entire pattern of the plate cylinder 39. In this case, the entire pattern receives different colors on the selective ink supply cylinders 34, 35, 36 and 37, but the ink on each selective ink supply cylinder 34, 35, 36 and 37 by the chablon rollers 40 to 43. Is selected, and only the necessary ink is transferred onto the collector cylinder 44. The advantage of this construction is that the selective ink supply cylinders are all the same and the manufacturing costs are reduced.

  The ink from each chablon roller 40, 41, 42, and 43 is then transferred onto the collector cylinder 44, which then supplies ink to the engraving 38 of the plate cylinder 39. As such, a wiping unit 45 common in the press technical field removes very little excess ink from the engraving and printing plate surface.

  Then, as is known in the printing art, the printing process itself is performed on the sheet 40 passing through the printing nip 41 formed between the plate cylinder 39 and the impression cylinder 42.

  The ink supply system of the present invention has many advantages, such as its simplicity and the significant ink savings it allows. Since the wiping action is not at the plate cylinder where all the colors of the ink are mixed and cannot be reused by the wiping operation, but at the stage of the ink duct, a serious amount of ink is not wasted. In this example, only very little excess ink is effectively transferred onto the plate cylinder, so that a minimal amount of ink is wiped off and lost.

  Of course, the above embodiments are given as non-limiting examples of the invention, and many variations are possible within the scope of the claims.

  For example, the ink supply system according to FIG. 2 can also be used in the construction of the printing press shown in FIGS.

  Preferably, the chablon roller is prepared in a conventional manner (chablon plate or continuous cylinder). An advantage of the present invention is that the amount of ink received by the edge of the area pattern of the chablon roller is minimal, i.e., a few micrometers thick. Thus, ink does not accumulate from the edge of the chablon plate to the recess and is much easier for the operator to clean.

Preferably, the engraved selective ink supply cylinder according to the invention does not comprise an engraving that exactly corresponds to that of a printing plate, but has a line characterized by: That is,
The same pattern as on the printing plate (excluding the required mirror image, ie whether the pattern engraved on the selective ink supply cylinder must be a mirror image of the engraving pattern on the printing plate).
It is larger than the engraving on the printing plate to ensure alignment of the markings on the printing plate and compensation for position tolerances.
Depth correlated to the depth of the line in the plate. In order to ensure that the proper amount of ink is transferred to the printing plate, it can be ensured that the engraving depth on the selective ink supply cylinder is, for example, about 30% greater than the engraving depth on the printing plate, In practice it is appropriate.
Engraved using the same technique as for printing plates.

  If a fine engraving pattern (depth is less than a few tens of micrometers, especially less than 10 micrometers) is provided in some areas of the printing plate, there is no need to engrave the corresponding areas on the selective ink supply cylinder, Engraving is provided only in the deeper area on the printing plate for ink supply. In fact, adapt the wiping system so that only a small amount of ink is left in the non-engraved area of the selective ink supply cylinder enough to supply ink for fine engraving on the plate cylinder You can also.

  It should therefore be emphasized that with respect to the patterns engraved on each selective ink supply cylinder, these engraving patterns are not strictly identical to the corresponding patterns on the printing plate. The expression “corresponding” used within the scope of this specification to describe the relationship between the engravings provided on the selective ink supply cylinder and the engravings provided on the plate cylinder is therefore between the engravings. Should be construed to mean that there is a slight difference in width, depth and / or position, although there is a substantial degree of similarity. Furthermore, as described above, the engraving may not be provided at all on the surface portion of the selective ink supply cylinder corresponding to the fine engraving on the plate cylinder. This is because the non-engraved area of the selective ink supply cylinder can hold a sufficient amount of ink to supply such fine engraving.

  In the illustrated embodiment, different ratios of barrel diameters are presented. For example, in FIGS. 3 to 5, the collector cylinder / chablon roller ratio is 3: 1, and in FIG. 2, this ratio is 2: 1. This should, of course, not be construed as limiting, but should be construed as indicating that different structures are possible, these are equivalent, and can be selected according to circumstances.

  As mentioned above, all cylinders with engraved surfaces may be engraved directly or the engraving may be held via clamping means.
